%RH set
Dehumidification setpoint
Default is 50 % RH
Conditional parameter to Humidity models
VTR735xX5x00(X)
Used only if dehumidification sequence is enabled:
Range is: 30-95% RH
DehuHyst
Dehumidification
Hysterisys
Default is 5 % RH
Conditional parameter to Humidity models
VTR735xX5x00(X)
Humidity control hysterisys. Used only if dehumidification
sequence is enabled:
Range is: 2 to 20% RH
DehuCool
Maximum
Dehumidification
Cooling output
Default is 100 %
Conditional parameter to Humidity models
VTR735xX5x00(X)
Maximum cooling valve position when dehumidification is
enabled. This can be used to balance smaller reheat loads
installed relative to the capacity of the cooling coil.
Range is: 20 to 100 %
St-By TM
Stand-by Timer value
Default 0.5 hours Time delay between the moment when the PIR sensor
detected the last movement in the area and the time when the
Terminal Equipment Controller stand-by mode and setpoints
become active.
Range is: 0.5 to 24.0 hours in 0.5hr increments
Unocc TM
Unoccupied Timer value
Default 0.0 hours Time delay between the moment when the Terminal
Equipment Controller toggles to stand-by mode and the time
when the Terminal Equipment Controller unoccupied mode
and setpoints become active.
The factory value or 0.0 hours: Setting this parameter to its
default value of 0.0 hours disables the unoccupied timer.
This prevents the Terminal Equipment Controller to drift from
stand-by mode to unoccupied mode when PIR functions are
used
Range is: 0.0 to 24.0 hours in 0.5hr increments
St-By HT
Stand-by heating
setpoint
Default value = 69 °F The value of this parameter should reside between the
occupied and unoccupied heating setpoints and make sure
that the difference between the stand-by and occupied value
can be recovered in a timely fashion when movement is
detected in the zone.
Stand-by heating setpoint range is: 40 to 90 °F
( 4.5 to 32.0 °C )
St-By CL
Stand-by cooling
setpoint limit
Default value = 78 °F The value of this parameter should reside between the
occupied and unoccupied cooling setpoints and make sure
that the difference between the stand-by and occupied value
can be recovered in a timely fashion when movement is
detected in the zone.
Stand-by cooling setpoint range is: 54 to 100 °F
( 12.0 to 37.5 °C )
